The purposes of these studies are to develop technologies to increase the sustainable production of soybean grains, minimizing stresses in lowland environment. The main results of this research will be presented based on the last decade of research, the date when returned soybean crop cultivation in this lowland environment in Rio Grande do Sul State. However, the soybean crop cultivation contains risks associated with the geographic location, characteristics of the soil and the chosen rice management, main culture in lowland areas. Thus the management practices must include minimizing the risks of water excess, especially drainage of the areas. On the other hand, the irrigation is essential for some regions due to rainfall behavior, or when high production expectation is set. Besides, aspects of soil conservation, such as minimum tillage and soil coverage must be studied, because the management of this crop yield in a condition of no irrigation is very different when compared to highland areas, which very little is known about. Concluding, the results presented by the papers are related to management practices aiming at getting better root environment, soybean nodulation, and tillage systems.
